A low pressure system will squeeze our persistent ridge of high pressure to the west and effect our weather for at least the next week and probably longer. The ridge of high pressure which can dominate our weather will be moved out of the picture allowing storms to come into our area from both the East and the West.

The following two images show the current conditions and conditions in about 4 days. Notice the high pressure ridge getting moved to the west:

This will usher in a change to our weather that will last into the foreseeable future.

Snow levels for these storms will vary from 8,000 to 10,000 feet. The blocking ridge of high pressure will allow moisture to be pulled into our area from the Gulf of Mexico ... again.

If you read our last post, then you were warned. Heavy, consistent rain has been falling for a couple of days now. This will continue through the weekend to some degree. Probably not as heavy or as consistent as what we have seen of the last 36 hours.

High pressure over New Mexico and Arizona is blocking a Low Pressure system located just off the Southern California coast. This is causing ample moisture to work its way back east into our area. Ironically, as this moisture hits the Carson range, it is somewhat shadowed. Very little of it is making it over the Sierra and into the California valleys where it is needed most. Northern Nevada had broken out of the drought a long time ago. I believe that the same holds true for Northern California but I will let the politicians, who know nothing, argue about that in the context of man-made Global Warming.

Here is a look at our current conditions. Notice the Low Pressure system sending moisture north and into our area and the Northern Rockie…

The Tahoe area and Leeward Valleys of Northern Nevada are in for a very rainy couple of weeks, at least. Several factors are involved, including off short troughs in the Pacific NW and inland troughs both southeast and northeast of us. Add a blocking ridge and we are going to see moisture coming from all directions.

Our top researcher, Paul H, had this to say about what to expect long term:

The wet pattern appears to continue till at least May 11 and is now indeed looking to be an interesting end to this interesting Super El Nino. I want to say I see a break in the Sierras from this wet cool weather but I'm not and it must be similar to what the dark ages were like in Europe- the summer solstice with frost and sleat. To be honest I believe the "sleep of the sun" (solar minimum) is playing a role in all this from the severe weird drought to extremely warm oceans to now this bizarre cool wet pattern I'm seeing continue into June. The Law of Thermodynamics and heat distr…

I am an avid Snowboarder. During the day I am a computer programmer (Web and Database development). I live in an area called Arrow Creek, which is located between downtown Reno and Incline Village at an elevation of 5,500 feet on the eastern front range of the Northern Sierra Nevada mountains.
When not snowboarding, I enjoy playing golf. In fact, my posse is made up of skiers, snowboarders and golfers. Where we live, you can oftentimes do both on the same day.
If you see a group of snowboarders and skiers flying down the slopes of Mt. Rose, that could be us. Please move aside as we may have a tee time to catch.
